About GD&T Advisor
Introduction
GD&T Advisor by Sigmetrix is an application that is integrated with
Creo Parametric that provides the following benefits when applying GD&T to your
design model:
• Creation — Efficient and intelligent application of functionally and syntactically correct GD&T in the 3D model environment.
• Validation — Visualization and function-oriented evaluation of GD&T.
• Education — Extensive help content and informative tooltips that aid in understanding of GD&T concepts.
• Reusability — Intelligent, CAD-native annotations are usable in downstream processes such as drawing production, tolerance analysis, computer-aided inspection, and other activities.
GD&T Advisor supports the ASME Y14.5-2009 and ISO 2011:2012 (and related) standards.
Help Pages of Interest
You should review and familiarize yourself with the following help pages:
• Limitations — As ASME Y14.5-2009 and ISO 2011:2012 are quite broad and complex, there are some other areas of those standards that are not fully supported. This document describes the limitations of GD&T Advisor. You should familiarize yourself with this information so you can understand how GD&T Advisor can be used.
Terminology Usage
The ASME and ISO GPS tolerancing standards involve many specialized terms. It is important that those terms are properly understood, so this document includes a glossary of terms (See
Glossary). In some cases, ASME and ISO use different terms for similar concepts. However, since GD&T Advisor uses the same user interface and documentation for both standards, in some cases the ASME term is used throughout the application and documentation, even in the context of ISO GPS. For example,
datum system is a term used in ISO GPS that has a very similar meaning to
datum reference frame in ASME, but
datum reference frame is used throughout the application and documentation. Thus, when working in ISO tolerancing standard, datum reference frame refers to an ISO datum system.
